Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154728, here are decompositions:

5 + 154723 = 154728
29 + 154699 = 154728
37 + 154691 = 154728
47 + 154681 = 154728
59 + 154669 = 154728
61 + 154667 = 154728
107 + 154621 = 154728
109 + 154619 = 154728

Showing the first eight; more decompositions exist.
